gfs_controld: fix fs_notify during recovery

Wasn't processing mountgroup again after an initial failed fs_notify,
so no retry was happening.  Also, the process_mountgroup check was
wrongly skipping the apply_changes phase sometimes at the very start
because there was no change struct yet, which would cause a segfault.
